Message board spam and e-mail spam are two different things. Here's the meaning of spam on PEEL from
the PEELer's FAQ. In short, spam is things that don't have anything or don't contribute to the thread. To almost quote the definition of spam you post, it's "like junk
e-mail posting."
For more questions, consult the PEELer's FAQ. It's your friend. Read it. Live it. Make a cult out of it.
Also, here's another
thread that says some of the PEEL Rules of the Road.
Also, I'm not blaming you for anything, but these are just some of the things PEELers before you have done that aren't good(Ex.- double/triple/quadruple posting, bumping a topic with "I agree.", etc.). Learn from their mistakes and don't get on a Mod's badside. Other than that, welcome to PEEL, and enjoy your stay at Nerd World.
